Slot Summary

Choose one of three covered options, and Koi Princess reveals which one-spin modifier will alter the next result. That small act of selection distinguishes NetEnt's anime and Asian pop-culture slot from a passive 20-payline format. Four possible outcomes can guarantee a five-symbol hit, place random Wilds, turn complete reels Wild, or activate the Bonus Wheel, while the triggered bonus path can lead to coins or two different Free Spins modes.

How It Plays

Standard combinations pay across 20 fixed lines on a 5x3 field. When the choice sequence appears, the player selects from 3 options before the revealed modifier changes one spin.

Possible outcomes include a guaranteed 5-symbol line, randomly placed Wilds, complete Wild reels, or direct access to the Bonus Wheel. The choice determines the concealed option, not its underlying result.

Theme & Atmosphere

Anime and Asia provide the main visual language, while Fantasy, Nature, Sea, and Queen motifs define the Koi Princess character and her surroundings.

Fruit symbols connect that character-led setting to traditional slot design. The contrast between familiar lower-value icons and the princess imagery keeps the crowded feature set readable.

Features & Win Potential

Wild Symbols substitute in line combinations, while the Spin The Wheel sequence routes a qualifying event toward coin awards or one of the Free Spins modes.

Scatter Symbols provide the triggered route to the Bonus wheel. Multipliers can appear among its outcomes, and the selected wheel result determines whether the feature ends or continues.

Bonus & Free Spins

The Bonus Wheel can award coins or open 2 Free Spins modes. Wild Reels Free Spins places complete Wild reels, with their number and positions changing between spins.

Sure Win Free Spins establishes a guaranteed-win reference from an earlier result and compares later outcomes against it. Additional Free Spins can extend the round when qualifying awards appear.

How this works

Each simulated spin either misses or returns a win drawn from a log-normal distribution, with the hit rate and spread set by the slot's volatility tier (Medium). The model is calibrated so the average return equals this slot's published RTP (96.23%), with wins capped at its top multiplier (1,000×).

This is a simplified, parametric model of the game's math — not its real paytable. It exists to make the house edge visible over many sessions, so the numbers above are averages across thousands of runs, never a forecast of one.

This is math, not a prediction. Real sessions vary wildly, and no strategy changes a game's built-in house edge. Play for fun, set limits, and never bet more than you can afford to lose.
